Title: Fuel arrangement for high temperature gas cooled reactor
IPC: G21C1/12
Filed: 1977-01-06
Abstract: 1507970 Reactors WESTINGHOUSE ELECTRIC CORP 6 Jan 1977 [6 Jan 1976] 00351/77 Heading G6C A fuel arrangement for a h.t.g.r. comprises a plurality of adjacent vertical columns (Fig. 1, not shown), each column comprising a stack of fuel assemblies, each fuel assembly, Fig. 3, comprising an elongated graphite moderator block 44 through which a number of spaced fuel passageways 50, 52 and a central control passageway 20 extend axially. Fissile fuel elements 42 (U-235) are removably received within passageways 50 while fertile fuel elements 40 (Th-232) are removably received within passageways 42, there being twice as many fertile elements 40 so fissile elements 42, the former being of smaller diameter than the latter. Fig. 5 shows a referactory fuel retainer 54 bonded to the bottom of each fuel passageway with an internal opening that exposes the end of a fuel element 40, 42, as allowing the element to be pushed out of the block 44 when so desired. A chamfered portion 58 of the retainer 54 ensures a continuous coolant path even if the fuel elements of a column are slightly misaligned. A removable retainer, such as one threaded or pinned into the block 44 at one or both extremities, could alternatively be used. A burnable neutron poison, e.g. boron, may be incorporated into the block 44 during manufacture. The fuel elements 40, 42 are extruded as elongated right circular cylinders each having a central circular coolant passageway and formed of fuel particles homogeneously distributed in a high density graphite matrix. A matrix of high density, e.g. 1À9 g./c.c., is attained by use of an 85 : 15 wt. ratio graphite flour/carbon black extrusion mix. The fuel particles (Figs. 7a, 7b, not shown) comprise a core of 93% enriched U-235, U-233 or Th-232 surrounded by a porous pyrocarbon buffer coat and a dense isotropic pyrocarbon coat, which in one form, are subsequently surrounded by a silicon carbide coat and an isotropic pyrocarbon caot. After a four year residence in the core, with a given fuel assembly progressing downward through the core until the fourth year when it is placed at the exit end of the core (Figure 8, not shown), the assembly is removed to an on-site hot cell where the spent fissile elements 42 are replaced with new fuel while the fertile elements 40 may be recycled.

Filed: 1932-01-11
Abstract: 395,344. Converting; discharge. apparatus. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Fitzgerald,. A. S. ; Warwick Road, Wynnewood, Pennsylvania, and Morack; M. M.; 900, Union Street, Schenectady, New York, both in U.S.A.) Jan. 11, 1932, No. 794. Convention date, Jan. 10, 1931. [Class 38 (ii).] Relates to an arrangement for preventing application of load to a discharge device until the cathode has heated to its normal operating temperature. A D.C. circuit 11 is supplied from an A.C. supply 10 through a discharge device 13 the cathode of which it is desired to protect. A switch 14 is held in the position shown by a spring 16 when the solenoid 17 is unenergized, and connects the main valve 13 and an auxiliary rectifier 32 of the copper-oxide type between a low voltage tapping 15 of the transformer 12 and the ends of a centre-tapped. saturating winding 26 of a choke 27 having windings 29, 30 which form a variable impedance shunt across the primary of a transformer 22. The current through the rectifier 32 is adjusted by a resistance 31 to a value equal to the current which flows through the valve 13 when the filament reaches its normal operating temperature. The saturation of the core 28 is dependent on the difference between the currents flowing in the two halves of the coil 26 so that the primary of the transformer 22 is practically short-circuited until these currents become approximately equal, at which point the relay 19 operates and completes the circuit of the relay 17 which closes the main switch 14. The switch 14 has auxiliary contacts 37 which are closed while the filament is heating and connect a positive bias to the grid of the valve 13. Additional contacts 39, 40 are arranged so that a negative bias is momentarily applied to the grid while the switch 14 is operating. In the final position of the switch 14 contacts 41 are closed connecting the grid to a source of control potential 42. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 397,154. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of filaments
Inventor: OCKELFORD PETER JOHN MAYHEW
IPC: D01D5/092
Filed: 1953-01-10
Abstract: In a process for the melt-spinning of synthetic linear polyamides into filaments of denier below 5 wherein the latter, on leaving the spinneret in the form of a bundle, pass, while in the process of solidifying, down a cooling shaft across which a current of gaseous cooling medium is maintained, the filaments after emerging from the spinneret traverse a vertical distance of at least 3 inches, particularly 3.5 inches \sB 0.5 inch, before first encountering the current of cooling medium.  The latter may be air, nitrogen, carbon dioxide or methane.  The polyamide may be polyaminononanoic acid, polyhexamethylene sebacamide, polyaminoheptanoic acid, polyhexamethylene adipamide, polycaprolactam, polypentamethylene sebacamide, polytetramethylene adipamide, polyoctamethylene adipamide or polydecamethylene adipamide.  In three series of tests polyhexamethylene adipamide yarns of 116 denier (as melt-spun) having 48 filaments, of 220 denier having 56 filaments and of 129 denier having 30 filaments, are made by melt-spinning the polyamide at 290 DEG  C. down a cooling shaft containing a cross-current of cool air, which is adjusted so as first to impinge on the filaments at 1.7, 2.7, 3.2, 3.7 and 5.2 inches vertical distance below the spinneret respectively in five separate runs.  The yarns are wound up at a speed of about 3,700 feet per minute and then cold-drawn at a ratio of 2.86.  It is found that the frequency of breakage of the filaments and of the whole yarn during cold drawing is reduced as the distance of the cooling current from the spinneret is increased.  The yarn is also capable of being more uniformly dyed.  Specification 533,304 is referred to.

Abstract: 480,400. Bookbinding. PARALLEX CORPORATION. Jan. 12, 1937, No. 921. Convention date, March 25, 1936. [Class 16] A bookbinding-machine for deforming the coils of a binding wire comprises a shelf 11, a rack A having a number of spaced presser bars 16 positioned in a plane perpendicular to the plane of the shelf 11, actuating means for the rack whereby the presser bars are moved in relation to the shelf while engaging the coils of a binding wire of a book upon the shelf to increase the obliquity of the portion of each coil projecting beyond the edge of the book, and means, such as a spring clamp, resisting movement of the book with the presser bars. Approximately an arc of 180‹ in each coil is distorted, and the remaining 180‹ is brought into a plane perpendicular to the axis of the binding wire, as shown in Fig. 5, whereby when the leaves of the book are turned, they will not move axially of the binder. The rack A comprises a fixed lower bar 12, an upper bar 13 pivotally connected to links 14, 15 pivoted on the bar 12, and the presser bars 16 which are pivotally and removably mounted at each end in the bars 12, 13. A wheel 23 carries a crank 24 adjustable radially thereof and connected to the link 14 by a pitman 25. The wheel may be driven, as shown, by belt-driven pulley 26 adapted to be clutched to the wheel on depression of a foot-pedal so as to make one complete revolution. The book 40 is placed on the shelf 11 over an adjustable gauge plate, so that the coils of the binding wire engage between the presser bars 16. A clamp bar 30 for the book is supported by arms 33, 34 carried by cranks 31 on a shaft 32 which is acted upon by torsion springs 35. The shaft 32 has a fixed crank arm 37 carrying an adjustable roller 39 bearing on the top rack bar 13 whereby pressure is only applied on the book when the bar 13 descends. When the machine is started, movement is imparted to the rack bar 13 by the pitman 25 to cause a tilting of the bars 16 about the fixed rack bar 12 whereby the obliquity of the portion of each coil positioned beyond the edge of the book is increased. The presser bars 16 do not affect the obliquity of the coils on the return movement since the clamp bar 30 releases the book. The machine parts are adjustable to accommodate and distort coils of different pitch and diameter.
